Suppression of unwanted signals.

EMI Filter for high-field MRI systems and sensitive imaging processes.

The MF420-2CF-M MRI Filter, from EMIS, is a specialised electrical filter for use in Magnetic Resonance Imaging rooms to block unwanted electromagnetic interference (EMI) and radio-frequency interference (RFI) from entering or leaving the MRI environment.

Designing or selecting an EMI filter for high-field MRI systems is very different from general electronics filtering as MRI environments are extremely sensitive to RF noise and require shielded-room integrity as well ultra-high attenuation across wide frequency bands.

EMI filters are critical in MRI High-field systems which operate with very low-level RF signals in an environment featuring strong static magnetic fields. External EMI contamination can degrade signal-to-noise ratio, create artifacts in images and cause regulatory non-compliance. Even cables entering the MRI room can act as antennas and leak noise into the shielded enclosure.

MRI EMC filters provide strong suppression of unwanted signals over a wide frequency range up to 10GHz, preventing external noise from affecting MRI signals and ensuring high-quality diagnostic images. These filters are typically installed at the point where power lines or signal cables enter an MRI shielded room, for example:
1. Power line filters - Main AC supply (single/three-phase), Gradient amplifiers, RF amplifiers.
2. Signal line filters - Ethernet / data lines, patient monitoring systems, fire alarms, intercoms, sensors.

MRI filters are specially designed to meet the strict performance requirements of equipment manufacturers and ensure compatibility with high-field MRI systems and sensitive imaging processes. The filter components are enclosed in a shielded and sealed metallic housing that protects against dust, moisture, and corrosion ensuring long-lasting performance.

Key features include:

• Connection via threaded conduit and flexible wire leads, allowing fast and secure installation in shielded MRI rooms.
• Designed with an internal discharge bleeder resistor that safely discharges stored electrical energy when power is turned off, reducing the risk of electric shock during maintenance.
• Designed with low leakage current, ensuring patient safety by minimising unintended current flow.

FeedThrough capacitors and filters.

Providing high frequency noise suppression and improved system EMI performance.

A range of FeedThrough components from EMIS, are designed to pass conductors through a grounded barrier while providing high‑frequency noise suppression and improved EMC performance.

FeedThrough Capacitors are a single capacitor mounted through a metal panel or chassis, allowing a signal or power conductor to pass while shunting high‑frequency noise to ground.​ This is highly effective at suppressing high‑frequency interference from approximately the kilohertz region up to the gigahertz range, depending on the construction and installation.​

The component provides a low‑impedance path to ground for unwanted high‑frequency signals, improving insertion loss at higher frequencies compared with standard two‑lead capacitors.​ It helps prevent radio‑frequency interference (RFI) from entering or leaving shielded equipment and enclosures.​

The design offers high reliability and mechanical robustness, suitable for harsh environments such as aerospace, military, industrial, and medical systems. Components are usually threaded for bulkhead mounting, ensuring a secure mechanical fit and a low impedance ground connection to the chassis or panel. The capacitor shell must be bonded firmly to the metalwork to maintain effective high frequency noise suppression; poor grounding significantly reduces performance.

Key features of FeedThrough Capacitors include:

• Typical current ratings to approximately 200 A and AC voltages up to 250VAC, depending on type and size.
• Capacitance values are available from approximately 2.2nF to 4700nF to support a wide range of impedance and attenuation requirements
• Devices are designed in accordance with IEC/EN 60384‑14 for safety‑related capacitors.
• Specified torque should be applied to threaded terminals and nuts to avoid mechanical damage and to guarantee stable contact resistance over lifetime.
• Versions are available that meet EMC and safety‑relevant capacitor classes (Y2) and/or specific pulse‑test or surge requirements.

A FeedThrough filter integrates capacitors and inductors, and in some design’s resistors, into a single housing to provide broadband attenuation of conducted noise Compared to a single FeedThrough capacitor, it offers higher insertion loss over a wider frequency range, often extending to lower frequencies where line impedance dominates.

Key features of FeedThrough filters include:
• Typical electrical ratings cover up to approximately 200A and AC voltages up to 250VAC, depending on the selected series.​
• Capacitance options generally range from about 10nF to 4700nF to optimise performance across different load conditions and noise spectra.​
• Designs comply with standards such as UL 60939‑3, IEC 60939‑1&2 and CSA C22.2 No. 8 for passive EMC filter components

FeedThrough EMC Components have a wide range of applications such as:

• RF & Communication Systems: preventing RF coupling through control and power penetrations in RF circuits, RF communication equipment, telecom base stations.​
• Power & Energy: reduce conducted emissions and improve immunity in switched‑mode power supplies, UPS systems, battery charging equipment, and electrical machines and drives.
• Aerospace: where high reliability FeedThroughs are required at bulkhead interfaces for avionics, radar, communication and mission‑critical electronics.
• Digital & Control Systems: High‑speed digital electronics, motor drives, robotics, PLC panels, as well as analogue and digital I/O lines that cross shielding boundaries.​
• EMC & Interference Protection: Broadband interference suppression for equipment needing stringent EMC compliance, including use in EMC chambers and shielded rooms.​
• Medical Devices: Implantable and external medical devices such as pacemakers and neurostimulators, where low leakage and high reliability are critical.​
• Noise Reduction in Panels: Suppression of noise on sensor, actuator, and control wiring routed near motors, inverters, and other high‑power switching elements.​
• Environmental Protection: Sealed bulkhead FeedThroughs are used to maintain environmental integrity while providing EMC filtering in harsh or outdoor conditions.​
• Networking & Communication: Where interfaces must pass through shielded enclosures without degrading EMC performance.​

EMIS aims to offer an end-to-end solution to meet industry’s ongoing EMI Challenges. With a robust global supply footprint across eight industry segments, EMIS is continuously investing in technology and skills to deliver its promise of efficiency with seamless customer support.

Filter options for machine builders.

Schaffner has extended its popular FN3270 series to provide more options for machine builders. Building on the strengths of the very successful FN3270 filter range the new FN3271 filter is an extremely compact and lightweight filter design requiring minimum mounting space in installations and cabinets.

15 different filter models are available to meet the specific needs and deployment for most industrial applications. These include industrial viable speed electrical power drive systems, motor drives and systems containing frequency inverters and servo drives.

With its enhanced performance the FN3271 offers an ideal solution for EMC challenges, where the impedance at the connection to the noise source is high (> 100 Ohm). The internal configuration of the FN3271 is optimised for this application. For applications with low impedances at the noise source the existing FN3270 remains the option of choice.

These new EMC filters provide the attenuation performance required to fulfil EN 61800-3/A11 and the filter performance is guaranteed under full load operating conditions. Solid, touch-safe terminal blocks are fitted to all filter models from 10 to 100 A, offering sufficient contacting cross section according to the EN 60204-1 installation standard.

To improve the safely of installations optional transparent protective covers are available for all filters with busbars from 150 to 1000 A.

EMC filter for LED lighting.

Schaffner has extended its range of filters for LED lighting applications with the introduction of the new FN2560 filter range. Specifically designed for attenuation requirements in the lighting industry the performance of the filter starts at frequencies as low as 9kHz. The new filter comes in an attractive space saving compact package and has single strand solid wire terminations providing simple, flexible and reliable installation.

Typical applications are LED equipment, LED driver and displays, streetlamps and signage, industrial and architectural lighting, fluorescent lamp ballasts or any other application requiring high differential mode performance. The Schaffner FN2560 has an operating temperature range of -40°C to 100°C.

At common mode attenuation performance, a choice of 3 different performance levels is available providing 3 different leakage ratings.

• C00: no leakage current, medical applications
• C11: low leakage current, safety applications
• C16: standard version, best filter performance

For applications where low reactive currents are needed, an alternative version “FN2564” is available. The FN2564 has no X-capacitance between grid and neutral line and has therefore no HF-current between the lines. This is helpful in applications with reactive current restrictions.

The FN2560 is suitable for typical European voltages of 300 VAC / 300 VDC and has current ratings of 1 A, 2 A, 5 A and 8 A, while the alternative FN2580 is rated at 350 V to suit typical international voltages.

EMC line filters.

Schaffner has released a complete range of their popular FN3280H 4-Line filter series featuring higher insulation resistances. This is a compact and lightweight filter design with a “cubic“ shape requiring minimum mounting space, simplifying the power entry design of enclosures and control panels for machine builders.

The new line-up of FN3280H filters, with the so-called R69 option, will not cause the overall insulation resistance of machinery or equipment when under test to drop below 1MΩ, ensuring systems fitted with the new EMC filter will  comply with European and International safety standards.  The filters also increase EMC immunity if connected directly to the mains input.

As a mains input filter for equipment requiring 3-phase power with a neutral line, the FN 3280 provides enough performance to ensure EMC compliance of machinery in mixed (Class A) or even domestic (Class B) environments while also increasing the immunity of the entire installation significantly. The new filter series is now available with power ratings up to 600A and the line-ground discharge time (after power disconnection) is increased so that standard models may be more suitable for non-machinery applications.

The FN3280 series provides the attenuation performance needed to meet the requirements of various machine tools with up to 12 driving axes and ~10 to 20m of motor cable each. To simplify selection for an application, the filter current ratings are aligned with common fuse values. The attenuation performance is identical to standard models making them interchangeable depending on end product application.

Providing simple and time-saving installation with good accessibility for automatic and hand tools FN3280H filters have solid, touch-safe terminal blocks (8 to 200 A types) offering sufficient contacting cross section according to the EN 60204-1 installation standard, commonly required for industrial applications.

Key specifications include maximum continuous operating voltage 3 x 520/300 Vac, operating frequency DC – 60Hz, rated currents 8 – 600A, operational temperature range -25⁰C to 100⁰C.

Typical applications include industrial equipment, machinery, machine tools and diverse process automation systems requiring 3-phase and neutral electricity supply. Due to the outstanding attenuation performance, FN3280 is also the first choice for noisy power supplies, renewable energy applications, high power office equipment etc. Because of the relatively low leakage current, FN3280 may even be used for some medical devices.

EMC filter -low leakage versions for RCD and medical applications.

Schaffner are reintroducing the FN2415 - single-phase EMC filter for control equipment with extended capabilities.

Large and complex machine tools with multiple driving axes and very long motor cables can be subjected to major reliability problems caused by internal coupling of interferences from the drive system to the control wires. This can cause dropouts and interrupts of the control unit and consequently lead to unnecessary and costly downtime of the entire machine.

The FN 2415 EMC filter, designed for the control line of complex equipment and machinery, eliminates interference affecting PLCs and motion or robot control systems, increasing the system stability and reliability of the entire machine. It can also be used for diverse single-phase applications, e.g. motor drives and power supplies.

Two new versions with adapted performance and lower leakage currents are now available. The FN 2415 B version with no leakage current (0 mA) does not add to the RCD total leakage current in a machine or a cabinet and may be used in medical equipment. And the FN 2415 L with leakage current of less than 3.5 mA for low leakage applications, allowing the use of RCDs rated at 30mA in complex machines where several 3.5mA leakage current filters may be connected in parallel.

With its excellent EMC attenuation performance, the Schaffner FN 2415 contributes significantly to the achievement of electromagnetic compliance, e.g. EN50370-1 standards for machine tools.

The compact design of the FN 2415 provides simple and time-saving installation with good accessibility for automatic and hand tools. Solid, touch-safe terminal blocks offer sufficient contacting cross section according to the EN60204-1 installation standard. The filters are IP20 rated and have an operating temperature range of -25°C to +100°C.

The filters have all the required safety approvals (UL, CSA and IEC / EN) and are compliant to REACH and RoHS directives.

High-performance filter with switch or fuse.

The high-performance filter series FN 9262 (with fuse holder) and FN 9266 (with dual pole switch), have been developed by Shaffner for applications demanding high RFI attenuation performance.

They represent an enhanced version of the already market proven FN 9260 and FN 9264 filter families. One of the key applications for this filter is the medical market and the filter carries additional approvals making it easier for the end users to implement into their designs. FN 9262 B and FN 9266 B (B-types) filters meet the insulation requirements according to IEC 60601-1 1MOPP (1 means of patient protection).

Both filter series outperform the existing filters FN 9260 and FN 9264 over the whole frequency range. This increased performance lies in two key components: the advanced core material (common mode performance) and the increased X-capacitor values (differential mode performance).

The housing dimensions are identical to the existing series making an exchange between the filters simple. In addition, the PEMs (Power Entry Modules) are mechanically compatible with almost all similar style products in the market and the same as the FN 9260 and FN 9264.

With the new variant diversity (FN 9260/2/4/6) and the present attenuation properties, this filter family offers a solution for medical devices, and modern appliances for household, audio and video. They can also be used in other applications with similar requirements.

The filters have all the required safety approvals (UL 60939-3, CSA C22.2 No. 8, IEC 60939-3 and CQC), they carry a CE mark and are compatible with the RoHS II (2015/863) directive.

The product range combines superior technology to reliably mitigate excessive harmonics with an evolutionary modular product concept and broadens the availability of Schaffner filter solutions for customers and applications.

The new ecosine evo FN 3442 and FN 3443 are dedicated passive harmonic filters for three-phase diode and thyristor rectifiers. They can achieve a THID ≤ 5% with and without a DC-link choke included in the drive. They guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards while being the most dedicated and compact passive harmonic filters available in the market. The filters offer excellent performance at rated power with minimal reactive power, even at partial or no-load conditions. When incorporating ecosine evo filters the electrical infrastructure is unburdened and its utilization is much more efficient and reliable. In addition, the service life cycle of electrical equipment is extended, and energy costs can be reduced.

Adding this extension to the existing six product families of ecosine evo filters FN 3440/41, FN 3450/51 and FN 3452/53, ecosine evo can now cover networks of 380 VAC to 500 VAC, 50 Hz/60 Hz.

Thanks to the modular concept including dedicated filters for drives without (FN 3440, FN 3450, FN 3442, FN 3452) and drives with (FN 3441, FN 3451, FN 3443, FN 3453) included DC-link choke ecosine evo filter series offers a market unique flexibility. It allows Schaffner to provide an optimal solution by offering base modules that are dedicated to the drive technology and can additionally be adapted to application and customer needs as well as installation requirements by simply “plugging in” add-on modules. The new Schaffner modular filters allows for the best tailored solutions for applications, aligning product offerings with international market requirements and customer expectations.

Ecosine evo filters FN 3442/43 are available with standard power ratings from 1HP to 240HP (0.9 to 177kW). They are available as open frame IP 00 (-E0XXXXX, -E0FAXRX, -E0FAJRX) and IP 20 (-E2FAJRX) versions. All FN 3442/43 filters are CE-marked, UL listed and RoHS compliant. Ecosine evo filters are easy to install and maintain. They are fully supported in Schaffner’s well known power quality simulator SchaffnerPQS3.
